The program-for-cache determining unit 107 counts the number of contents (a corresponding contents number) that are to use reproduction programs, for each reproduction program transmitted over each channel during the current service period and onward up to the last service period shown in the broadcast information, and determines a reproduction program that has the highest corresponding contents number, as the one to be cached. The program-for-cache determining unit 107 also determines the service period and channel during and over which the determined reproduction program is to be cached. The cache unit 108 instructs the demultiplexing/decoding unit 104 to demultiplex and decode the reproduction program corresponding to the determined channel and store it in the reproduction program storage unit 109.
